Environmental Sensitivity Index Maps
Environmental Sensitivity Index Maps (ESIs) were most recently developed for Maine and New Hampshire in 2016 by the National Oceanic and Atmospheric Administration's Office of Response and Restoration. These maps provide a summary of biological, geological and human use resources that are at risk if an oil spill occurs nearby. On a PC, they can be best viewed by downloading a zip file of PDFs (219 MB) from the NOAA website and opening the Index map. This zip file contains the legend and other supporting data. Alternatively, the ESIs can be viewed on the web through NOAA's Environmental Response Management Application (ERMA).
Maine Environmental Vulnerability Index Maps
Maine developed the Environmental Vulnerability Index in 2007 to depict the biological, geological and human resources along the coast of Maine most at risk from oil spilled into the marine or estuarine environment. It is important to note that these maps are not an exhaustive inventory, but are a survey meant to give first responders a tool for prioritizing and targeting protection strategies.
